T0 r/ZZ when?, rit may concern.-

Be it known that I, WILLIAM OsoAR SHAD- noLT, a citizen of the United States, residing in the borough of Brooklyn, in the county of Kings and city and State of New York, have invented certain new and useful Improvements in Dumping-Vagons, of which the following is a specification.

This invention relates to the class of fourwhceled dumping-wagons wherein the dumping-body is moved to and fro on the frame for dumping and replacing by suitable crank-operated mechanism on the frame.

The purpose of the present invention is to provide separate simple means for moving the body to and fro which shall be substantially independent of each other and operatable from different points, whereby when the body dumps it shall not communicate its movement to the operating mechanism employed for dumping, as will be hereinafter fully explained.

In the accompanying drawings, which illustrate an embodiment of the invention, Figure l is a side elevation of the dumping-wagon, showing the body in its normal position on the frame. Fig. 2 is a similar view showing' the body dumped. In both of these views `some parts are broken away the better to illustrate the' construction.

Fig. 3 is a transverse vertical section taken at line fr in Fig. 2. Fig. I an under side view of the frame and the dumping andreplacing mechanism. Figs. 5 and 6 illustrate a modilied form of the dumping devices. Fig. 7 is a fragmentary View showing the pusher on the rack engaging the body near the dumping-fulcrum thereon.

In this class of wagons it is very important that the dumping and replacing means shall be simple, strong, and durable and that when the body dumps the movement shall not be communicated to the hand-operated mechanism used by the driver or attendant in dumping, and the mechanism now to be described provides such a construction.

In Figs. l to 4 of the drawings, l designates the frame of the wagon supported in the usual manner on wheels 2. As the frame and wheels may be of substantially the usual construction and the frame may be mounted on the axles `through a fifth-wheel and springs of a known kind and construction, no special description of these parts will be required.

3 designates the dumping-body slidable on the frame. At the sides of the frame, near the hinder end thereof, are two roller fulcrumstuds 1i, one at each side, and at each side the body 3 has rigidly secured to it a keeper 5, which is engaged by one of said fulcrumstuds--that is to say, under the bottom side rail of the body is secured the elongated keeper 5, which may be conveniently of iron er steel-and this keeper forms a limitingslot along which the fulcruni-stud 4 plays when the body is being moved to and fro for dumping and replacing. The body can only move so far as these keepers 5 will permit.

The mechanism for dumping the body and replacing it comprises two substantially distinct devices. A shaft 6, rotatably mounted in and extending across `the frame, has a square on itsend to receivea crank 7 for rotating it, and this shaft serves as a barrel, on which wind two chains 8, each being attached to a sliding pusher 9, which plays loosely along a guide-channel l0, secured to the frame. As seen in Figs. l and 2, the pusher 9 has an upright 9, which takes in front oll the body 3 when the latter is in its normal position on the frame, as in Fig. l. To dump the body, the crank is placed on the shaft 6 and the latter rotated in a manner to wind up the chains 8 thereon. This has the effect to move or draw the pushers 9 to the rear and to slide the body 3 to the rear through the engagemcntof the uprights thereon with the front end of the body. The body moves back until it becomes overbalanced, when it dumps to the position seen in Fig. 2.

This dumping is effected without in any way or degree communicating its movement to the shaft 6 or to the \vin .lingcrank.

Mounted rotatvely in the frame at a point farther to the front than the shaft 6 is another shaft 11, also provided with a square at its end to receive the crank. Chains l2 connect this shaft with the bottom of the dumping-body 3 at a point forward of the `Fulcrum, about which the body dumps, as clearly shown. In order to replace the body, the crank 7 is placed on the shaft 1l and the chains l2 wound upon the latter. The iirst IOO effect of this is to right the body by drawing down its forward end until the said end takes its place behind the uprights 91 on the pushers and then to draw the body forward on the frame to the position seen in Fig. 1.

It will be noted that when the body dumps it unwinds the chains 12 from the shaft 11 by rotating the latter and that when the body is replaced it unwinds thc chains 8 from the shaft 6 by rotating the latter. It is preferred to employ a pair of chains 8 and a pair of chains 12; but the number of chains used or whether some other form of iieXible connectors than chains-as wire ropes, for example-be employed is not material to the present invention.

Then the body is replaced and occupies the position seen in Fig. 1, it may be held against accidentally sliding back by any suitable means.

Fig. 5 is a fragmentary side view, and Fig. 6 a vertical cross-section at line fc in Fig. 5. In this construction the chains 8 are substituted by a toothed rack 8 on the pusher 9 and a pinion 6u on the shaft 6. The rotation of the shaft 6 acts through the pinion and rack to move the pusher to the rear just as the chains 64 in the principal figures act as connecting means between said shaft 7 and the pusher 9. It will be noted that the means for moving the body 3 back to the point where it dumps is confined wholly to the frame and is not coupled in any way to the body, so that when the latter dumps it is put out of operative connection with the pusher or moving means. This body-moving means is, in fact, only in operative relation with the body when the latter is supported on the frame in a nearly horizontal position. Vhen the body dumps, the part of the body which is engaged by the pusher is moved upward out of thc path of the latter. It is not important to this invention at what point the pusher engages the body or a part thereof. 1f this point of engagement be back near the dumping-fulcrum, the upward movement of the body may be correspondingly slight in extent; but in any case the pusher will not be in operative connection with the body when the latter is dumped. Fig. 7 shows a construction where a pinion 6u on the shaft 6 operates to drive rearwardly a rack 8, guided in the frame, said rack carrying at its rear end a pusher 95, the concave face of which bears on a rounded part 3" on the body at the normal fulcrum-point, about which the body turns in dumping.

Having thus described my invention, l claiml. A dumping-wagon having a frame, a body movable rearwardly on said frame to the du mping-point, and means for moving the said body back to the d umping-point, said means having a pusher which takes in front of a part of the body and is mounted slidably on the frame, and said pusher being in operative relation with the body only when the latter is supported normally on the frame.

2. A dumping-wagon having a frame,a body movable rearwardly on said frame to the dumping-point, and means for moving the said body back to the dumping-point, said means having a pusher which takes in front of a part of the body and is slidable on the frame, and said part of the body engaged by the pusher being movable upwardly out of the path of said pusher when the body dumps.

3. A dumping-wagon having a frame, a body movable. rearwardly on said frame to the dumping-point, means for moving the said body back to the dumping-point, said means having a pusher which takes in front of a part of the body and is mounted slidably on the frame, and said pusher being in operative relation with the body only when the latter is supported normally on the frame, and means separate and independent from the means above described for replacing the body.

1. A dumping-wagon, having a frame,a body movable on said frame rearwardly to the dumping-point, a shaft mounted rotatively in the frame, a.pushing means mounted slidably in the said frame to move from front to rear, and adapted to take in front of some part of said body for pushing the latter back to the dumping-point, and a chain coupled at one end to said pushing means and at the other end to said shaft for winding on the latter.

5. A dumping-wagon having a frame,a body mounted movably on the frame for dumping, means for pushing back the body on the frame to the dumping-point, said means comprising a shaft rotatively mounted in the frame, a chain connected to and adapted to be wound on said shaft, a pusher in a guide on the frame and connected to said chain, said pusher taking in front of some part of the body, and the said guide, and means independent of the dumping means for replacing the body after dumping.

6. A dumping-wagon having a frame,a body mounted movably on the frame for dumping, a rotatively-mounted dumping-shaft 6 in the frame, chains 8, secured at one end to said shaft and at the other end to pushers 9, they said pushers, guides 1() for said pushers, a replacing-shaft 11 mounted rotatively in the frame forward of the shaft 6, chains 12 secured at one end to the shaft 11 and at the other end to the body forward of the dumping-point, anda crank for rotating' said shafts, the pushers having uprights which take infront of some part of the body for pushing it back.

1n witness whereof I have hereunto signed my name, this 13th day of January, 1904, in the presence of two subscribing witnesses.
